As some will know 18650 battery fakes are all about, these come in a white box with simply 25R on them, if you peel the sticker back you will be able to read the info, mine were dated early 2016 which is to be expected considering shipping out of China and then the stock level you have to buy to get good prices, I had one issue with one pair I bought, they didn't appear to be re-charging after I'd run them right down almost, a quick take out put back in sorted that and I up'd my charger to run 1A rather than 0.5A, 100% certain they are genuine and my VTC4's I had from elsewhere last year also came without labeling in plain boxes and again a vendor that is too large to be messing about with fakes, so to sum up, a pair lasts 12 hours in a 213 mod averaging around 40w heavy vaping, buy with confidence.
